In the face of declining print revenue, many publishers are adopting paywalls to monetize their content, which require users to either register or pay for access. Paywalls can be categorized as hard or soft, with examples from major publications like The New York Times, which has seen significant increases in subscription rates. While paywalls can generate predictable income and allow for data collection, potential downsides include reduced visitor numbers and the challenge of providing content that justifies the cost to subscribers.
